SPECIFICATION forming part Of Letters Patent NO. 640,997, dated January9, 1900.

Application filed August 8, 1898. Serial No. 688,104, o modem To aZZwhom it may concern.-

Be it known that 1, WILLIAM W. Dmenn, a resident of Racine, Racinecounty, Wisconsin, have invented certain new and useful Improvements inThreshing Machines, of which the following is hereby declared to be afull, clear, and exact description.

The present invention has for its object to provide various improvementsin threshingmachines, which improvements are hereinafter fullydescribed, illustrated in the accompanying drawings, and particularlydefined in the claims at the end of this specification.

Fig. 8 is a detail view showing the manner of connecting the conveyer extension to its supportingrail. Figs. 8 and 8 are detailviews of shoes at the sides of the conveyer extension. Fig. 9 is a viewin vertical cross-section through the sieves and parts at'each sidethereof, the section being taken on line 9 9 of Fig. 10. Fig. 10 is anenlarged detail side view of that part of the machine at the point wherethe sieves are adj ustably sustained. Fig. 11 is a detail inner faceView of the clamp-shoe, whereby the sieve-sustaining rods are adjustably supported. Fig. 12 is a detail View in vertical section on line12 12 of Fig. 10.

A designates the body of the machine, at the front end of which ismounted the threshing cylinder B of familiar construction. /Vithin thebody A is sustained the strawrack 0, this rack being mounted upon usualrocker-arms, whereby motion is communicated to the rack in manner wellunderstood 'clined bars 0.

in the art. The straw-rack G is provided with the usual inclined barsc,that support the cross-slats 0'. Prior to my present invention it hasbeen the practice to provide inclined bars 0 and slats o and to extendbetween the bars 0 the slats c to points beneath the in=. An objectionincident to such prior construction is that there was a tendency of thestraw to accumulate upon the slats beneath the inclined bars 0, thuspreventing the grain from falling through the rack onto the conveyorbeneath it. In order to overcome this objection, I have provided theforwardlyinclined risers 0, between which, from side to side of therack, extend the slats 0 these risers O and the slats a serving asguards to prevent the accumulation of straw beneath the inclined bars 0and slats c of the straw-rack.

In order to cut the twine or bands whereby the bundles of grain arebound, it has heretofore been the practice to provide the hopper with aseries of band-cutting knives D, (see Fig. 2,) mounted upon bars at, towhich a compound movement was imparted through the medium of suitablecranks d. In practice it has been found. that with such construction itnot infrequently happens that bands will escape being cut, therebycausing danger of the clogging or inefiicient action of thethreshing-cylinder. It has also been the common practice to provide themovable hopper-bottom E with vertical saw-tooth blades E for advancingthe grain toward the threshingcylinder. To secure the more edectivebreaking up of the bundles and insure the cutting of the bands, I haveprovided the saw-blades E with supplemental band-cutters E these cuttershaving reversely inclined cutting edges, as clearly seen in Fig. 2 ofthe drawings. The result of this construction is that as the bundles arefed by the endless carrier X into the hopper the supplemental cutters F.insure the cutting of all bands and also aid in breaking up the bundles,so as to more effectively present them to the threshing-cylinder B.

Inasmuch as the bundles of grain often vary in size, it is highlydesirable, to insure the effective feeding of the grain through thehopper and to the threshing-cylinder, that provision be made foradjusting the swinging rods whereby the rear ends of the rake-bars andthe band-cutters are carried. To accomplish this, the upper ends of theswinging rods D are pivotally connected to a vertically-adjustablecross-bar D (See Figs. 2 and 3.) Preferably the upper ends of the rods Dare bifurcated and are mounted upon a rod 61 that passes through thedepending end portions of the cross-bar D To secure the verticaladjustment of the cross-bar D this bar is shown as provided at each endwith a bolt d passing therethrough, each of the bolts d also passingthrough holes 01 formed in one of the vertical posts D at thecorresponding side of the machine. It will thus be seen that by shiftingthe bolts 61 to higher or lower holes 61 of the posts D the rear ends ofthe bars d can be raised or lowered to suit the sizes of bundles thatmaybe delivered to the machine. The hopper-coverD is hinged, as at d,and the lower free end of the cover rests upon the top of the cross-barD*, so that as the cross-bar is raised or lowered the cover D is carriedwith it. v

In order to more effectively keep the chaff out of the tailings and toprevent grain being carried away with the chaff, I have provided theconveyer extension, next to be described. By reference to'Figs. 1 and 5to 8 of the drawings it will be seen that the side rails F of theconveyer that extends beneath the straw-rack Gare formed with theoutwardly-extended rail-sections F,theserail-sections beingshown asbolted to the under side of the conveyerrails F. Between the railextensions F and at the rear end of the usual conveyer-sieve F ismounted the conveyer extension that is shown as consisting of end barsG, between which extend the cross-slats these slats having preferablyinclined upper surfaces, as shown. I prefer to provide metal plates G atthe sides of the bars G and to connect the conveyer extensionto the railextensions F, as more particularly shown in Figs. 5, 7, and 8 of thedrawingsthat-is to say, each rail extension F has attached to its freeend the metal shoe K, formed with a slot is, that coincides with asimilar slot cut in the end of the rail F. The slots it serve to receivethe pivot-bolts M, whereon the conveyer extension is adj ustablysustained. The outer face of each of the shoes K is shown as formed witha transverse rib adapted to set within the corresponding groove 70 thatis formed in the inner face of the guard-plate K, through which the boltM passes and against which the head of the bolt bears. Each of the shoesK has its ends formed with inwardly-projecting flanges or the desiredangle it may be there securely retained.

From the foregoing description it will be seen that as the chaff passesover the conveyer-extension the tailings will fall therefrom between theslats g. If, however, it is found that the grain is being carried offwith the chaff, the operator will turn the conveyer extension from theposition shown by full lines toward the position shown by dotted linesin Fig. 5 of the drawings. The effect of this inclination of theconveyer extension will be to retard the outflow of the grain and chaff,thereby securing their effective separation and preventing the grainpassing off with the chaff and as well also keeping the chaff out of thefailings. It will be understood, of course, that the adjustment of theconveyer extension will. be in keeping with the character and conditionof the grain being operated upon; but by loosening the thumb-nuts m theconveyer extension may be turned to any desired position, after which bytightening the thumb-nuts it will be securely retained in place. Byforming the rail extensions F with open slots at their ends it will beseen that the conveyer extension can be readily removed when desired.

The rear end of the conveyer extension is shown as provided with across-bar f that carriesadependingcanvas flap f that serves to directdownward and onto the plate 0 any tailings' passing through the rearportion of the conveyer extension, the plate 0 serving in turn todeliver suchtailings into the tailings-trough P, whence it will beremoved by the augerP. The bar f is shown as attached to the side bars Gof the conveyer extension by bolts f and thumb-nuts f In order to permitthe deflecting-plate O to be adjusted in keeping with the adjustments ofthe conveyer extension, I have provided at each side of the main framethe rearwardly-extendi'ng plates R,that are formed with notchesr,adapted to receive the bolts or pins 0, that project from the bars 0at the top of the deflectingplate 0. Thus by reference to Fig. 5 it willbe seen that when the conveyer extension is in the approximatelyhorizontal position there shown the deflecting-plate 0 will be sustainedfrom the lowest notches r of the plates R, but when the conveyerextension is inclined-say to the position shown by dotted linesthedeflecting-plate 0 will be correspondingly raised and its bolts 0 willrest in the uppermost notches r of the plates R.

In order to enable the sieves S to be adjusted in keeping with thecharacter of the grain being, operated upon so as to insure a moreeffective separation of the grain, I have provided the means illustratedmore particularly in Figs. 9 to 12 of the drawings. In

each side wall A of the main body of the machine, at points opposite theforward ends of the sieves S, are formed the long slots a and oppositethese slots are attached the ICC.

plates T, having the slots t, that coincide with the corresponding slotsa Through the slots a and t extend the rods W, that extend beneath andserve to support the forward ends of the sieves S. The outer endsof eachof the rods W pass through adjustable guardplates V, and arescrew-threaded to receive the thumb-nuts 1w, that serve to tightly holdthe guard-plates V in position upon the plates T. By reference to Fig.11 it will be seen that each of the guard-plates V has its inner faceformed with a groove 17, adapted to set upon the transverse ribs t ofthe plate T, and at the ends of the guard-plate V are formed the flanges42 that bear against the sides of the plate T and prevent the turning ofthe guard-plates when the thumb-nuts are tightened. The guard-plates Vare preferably of such width as to fit between adjoining ribs 15 of theplate T, and hence the rods W, and consequently the sieves sustainedthereby, can be adjusted to any points corresponding to the transverserib t or to the space between said ribs. In order to enable the operatorto readily effect the adjustment of the sieves, I form the sides A ofthe machine adjacent the plates T with a series of holes 12corresponding in number and arrangement to the ribs 25 and intermediatespaces of the plates T, as clearly shown in Fig. 10 of the drawings, andthrough the hole 1 will be inserted the supporting-pin Y, the inner endof which will serve to temporarily sustain the adjacent side of thesieve while the rod W is being adjusted. To-prevent the loss of pin Y,it is shown as attached to a cord y, the outer end of which is securedto the side of the machine. The rear ends of the sieves are sustainedupon pivot-rods in the usual manner.

From the foregoing description it will be seen that when it is desiredto change the inclination of the sieves the operator will set the pin Yinto the hole 'y corresponding with the point at which it is desired toset the sieve. Having done this, he can loosen the thumb-nut w of therod W and permit the sieve to rest upon the inner ends of the pins Y.The operator will then set the guard-plates V at the desired point uponthe plates T, and by tightening up the nut to will securely fix the rodsat the point at which it is desired to sustain the sieves. In practicethe pins Y are found highly advantageous, since they relieve the rodsfrom the weight of the sieves during the adjustment of the rods, andthus enable the operator to much more readily effect the adjustment ofthe sieves.

While I have described what I regard as the preferred embodiment of myinvention, it will be readily understood that the details ofconstructionabove set out may be varied without departure from the scopeof the invention and that parts of the invention may be used without itsadoption as an entirety.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
